Integration of Google Publisher Tag - flutter

Integrating Google Publisher Tags (GPT) from Google Ad Manager (GAM) into a Flutter application involves setting up GAM, integrating the GPT library, defining ad units, and testing ad delivery. Here's a step-by-step guide to help you integrate GPT and test ad delivery in your Flutter application:

Step 1: Set Up Google Ad Manager (GAM)

1. Create a Google Ad Manager account if you don't have one: https://admanager.google.com.
2. Set up an application in GAM and create ad units as described in previous sections.

Step 2: Integrate Google Publisher Tags (GPT) Library

1. Add the google_mobile_ads package to your pubspec.yaml file:

   dependencies:
       flutter:
           sdk: flutter
       google_mobile_ads: ^latest_version

2. Run flutter pub get to install the package.

Step 3: Configure GPT in Your Flutter App

1. Import the necessary classes in your Dart file where you want to display ads:

   import 'package:flutter/material.dart';
   import 'package:google_mobile_ads/google_mobile_ads.dart';

2. Initialize GPT with your Ad Manager ad unit ID and ad size:

   final String adUnitID = '/YOUR/AD_UNIT_ID';
   final BannerAd bannerAd = BannerAd(
   size: AdSize.banner,
   adUnitId: adUnitID,
   listener: BannerAdListener(),
   );

3. Load and display the ad:

   bannerAd.load();

Step 4: Test Ad Delivery

1. Use Google's test ad unit IDs for testing. Replace "YOUR/AD_UNIT_ID" with the appropriate test ad unit ID:
   • Test banner ad: /6499/example/banner
   • Test interstitial ad: /6499/example/interstitial
2. Make sure you are not using real ad unit IDs during testing to prevent serving live ads.
3. Run your Flutter app on an emulator or a real device to test the ad delivery. Ensure you have an active internet connection.

Additional Steps

• Implement GPT ad event listeners to handle ad lifecycle events, such as ad loaded, ad clicked, etc.
• Test different ad formats, sizes, and targeting options using the GPT library.
